T 0 all whom it may concern:

Be it known that I, JOSHUA C. "REYNOLDS,

a citizen of the United States, residing at Owensboro, in the county of Daviess and State of Kentucky, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

My present invention relates to oil burners and has for its object the provision of a simple and compact burner whereby liquid fuel may be readily converted into a combustible vapor and heat-economically generated thereby. Another object of the invention is to provide simple means whereby the 5 heat may be most advantageously utilized.

Incidental objects of the invention will appear in the course of the following description. I

In the annexed drawings:

Figure 1 is a plan view, partly broken away, of one embodiment of my present invention;

Fig. 2 is a side elevation of the same with part in section;

Fig. 8 is an enlarged detail section on the line 33 of Fig. 1;

Fig. 4 is an enlarged detail horizontal section on the line 4-4 of Fig. 2, and

Fig. 5 is a detail section showing a burner tip differing from the form shown in Fig. 1.

In carrying out my present invention, I

provide a volute coil 1 which maybe con-- nected directly with a supply pipe 2 leading from any convenient reservoiror source of supply. The several turns of the coil 1 will obviously successively decrease in diameter, the innermost turn of the coil defining an open space, indicated at 3, through which the flame from'the jet spout 4 may rise. From the inner extremity of the coil the pipe is carried downwardly, as shown at 5,-

and connected directly with a cut-off and regulating valve 6 which may be of any approved type. mediately adjacent the jet spout 4 which extends from one end of the valve casing and projects upwardly, being equipped with a jet opening 7 in its upper end. The stem of the valve 6 projects through and below'the valve casing is flat-sided, as shownat 8 This valve 6 is arranged im-' Application filed June 16, 1924. Serial No. 720,312.

in Fig. 4, whereby it may fit closely a slot 9 formed in the innerend of a handle or adjusting bar 10 which projects laterally from thevalve to any desired extent and permits the valve to be easily adjusted without the user being directly exposed to the heat immediately at and adjacent the valve.

To maintain the operative relation and en gagement of the handle member 10 and the valve stem, a connecting pin 11 is inserted through the stem and the end of the handle, as clearly shown in Fig. 4.

The coil 1 is supported by a plurality of legs 12 which also support an ignition pan 13, the said pan being provided at intervals with off-set lugs 14 having openings vertically therethrough to receive the legs 12, and

set screws -15 being mounted in the said lugs to bear against the legs and thereby secure the pan in the proper position thereon. The

pan, will, of course, be arranged below the spout 4 so that the liquid fuel which may be permitted to overflow from the said spout," when startingthe use of the burner, will be caught in the pan. The upper pore tions of the legs 12 are carried laterally radially outward, as shown at 16, and the coil 1 rests directly upon these lateral-portions. The extremities of the legs are turned upward, as shown at 17 to abut the outermost turn of the coil, and clamp plates18 are fitted upon the said upturned terminals 17 and project inwardly therefrom over the outermost-turn of'the coil 1, the inner edges of said clamp plates being turned slightly downward, as shown at 19 in Fig. 8, whereby they will closely engage the circular surface of the coil pipe and will very securely hold the same to the supporting member 16 when the nut 20 which'is mounted upon theterminal 17 is turned home.

In order to retard the-flow of fuel through the coil and thereby assist in the vaporization of the same, I prefer to insert in the inner turns of the coil acable 21 which may be of metallic material and which, when it is used, should extend vfrom the end of the innermost turn ofthe coil to a point in the coil near the outermost turn of th samecourse, the extent of 'thls the li aid in plan view, the arms and the'plate being preferably cast as one integral structure. The arms have parallel edges 24 either of which may rest upon the coil 1 and said edges terminate in abutments which conform to and'are adapted tofit against the outermost turn of the coil 1 whereby the baffle will be support-edover the coil in axial 'alinement with the jet spout l. 'Ob viously, -when'thebuiuier is in use, the flame rising from the spo'ut4willpl'ay upon thebai'fie 22 'andwill be'thereby diverted or spread'laterally 'sothat'it will then play over theupper surface of the coil land 'raise'the'temper'ature th reof so'that the liquid fuel flowing ii'i'to 'and through the coil will be vaporized quickly and will be very easily and efficiently "ignited'asit issues from the jet spout. If the curved surface of the battle he presented to thecoil, the flame may pass more directly upward-from the coil'but, if the flat "face of thej bafl'le be presented to the coil, "the flame will beheld more closely to the coil and, consequently, the fu'e-lwillbemore fguickly vaporized. The intensity of the "flame may {thus be regulated and the 'heat there-from utilized in the manner which may prove 'most efiicient under any given circumstances. Of course, the intensity-of the name willbe' also to agreat extent regulated by the adjustment of the valve 6. The legs 12 may'rest upon a stovetop or any other fixed support and will carry the coil and the burner in such a manner that they will be "fir mlysupported but at thesame time will be readily accessible at all times to facilitate cleaning or repairs.

WVhen the burner is to operate, a small portion of the fuel may be permitted to overflow into the ignition pan 13 by opening thevalve 6, or the pan'may be otherwise filled The fuel in the pan is ignited and the flame therefrom will play'direc'tly upon the spout 4 and the pipe 5 leading thereto so that the body of fuel in the pipe will be quickly vaporized. -If the valve 6 be then 'op'ened,'this vapor will issue at the opening ofthe jet-spout '4: where it *may be ignited and the burner will then continue to gen- 'erate and consume the'combustible vapor as long as the valve is permitted to remain open. "The burning vapor will, ofvcourse,

possess some velocity so that the greater portion thereof will pass through the opening 3 and play upon the baffle which will divert it so that it plays over the coil 1 to assist in vaporization of the fuel flowing therethrough before rising around the battle to be utilized in cooking or heating. The battle and the arms extending therefrom will become heated asthe operation of the burner continues and the heat "thus stored in said elements will'react Ont-he coil so as to aid in the vaporization of the fuel, and in a to the'inner terminal 5 of the coil, a jet plug 31'being secured in the upper side of the bowl and a drain plug 32 being secured in the under side of the bowl in axial *alin'ement with the jet plug. Suitable packing, indicated at 33, is provided to prevent leak age around the plugs.

Having thus described the invention, I claim:

burner comprising a volute coil connected with a source'of supply, a jet spout arranged below and in communication with the coil, supporting legs below the coil having their upper portions extending laterally outward whereby to :bear against the under side of the coil and having their upper terminals upturned to abut theoutermost turn ofthe coil, clamp plates mounted upon said upturned terminals and engaging over the outermost turn ofthe coil, and securing devices mounted upon said terminals and bearing upon sald clamp plates.

2. A burner comprising a volute coil connected with *a'source of supply, a et spout arranged below the coil and 'communlcatlng therewith, supporting legs connected at-their upper ends with the coil, and an ignition pa n provided with lateral lugs through which the legsextend and having set screws mounted in said lugs to bind upon said legs.

3. A burner comprising avolute coil having its outermost turn connected with a source of fuel supply and having its inner most turn defining a central clear space, a jet spout arranged below the coil and in communication with the innermostturn of thesaine, means for supporting the coil, a battle arranged above the central space of the coil, and arms extending radially from the baffle to rest on the coil and engage around the outermost turn of the same.

4. A burner comprising a Volute coil having its outermost turn connected with a source of fuel supply and its innermost turn defining a central clear space, a jet spout arranged below the coil and in communication with the innermost turn thereof, means for supporting the coil, a reversible bafile ar:

ranged above the coil and over the central edge may rest upon the coil, said edges terminating in abutments adapted to engage the outermost turn of the coil.

In testimony whereof I aflix my signature.
